Question

当我尝试mariadb-server使用以下命令在 Ubuntu 21.04 上安装时：

sudo apt install mariadb-server

它显示了这个错误：

Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:

The following packages have unmet dependencies:

Answer 2

你应该有一个可用包在通常的仓库中。

您收到的错误消息可能由多种原因引起。您可以尝试以下方法来解决问题或找出原因：

1. sudo apt update安装之前。
2. sudo apt autoremove之前update。
3. 列出保留的包裹dpkg --get-selections | grep hold（或dpkg --get-selections | grep "\<hold$"按照这）。
4. sudo apt-get -f installmariadb-server`强制安装。
